Mouse Cursor Hidden -> duplicate of #7945.

[kingbeandip]

On my machine the mouse cursor is invisible (clicking, hover events, dragging, etc all work, but I cannot see the cursor) when the VM captures the mouse. This happens both when Mouse Integration is turned off, and when I attempt to assign a second mouse to the VM (in the Devices menu). Mouse integration works normally, but this prevents me from dedicating a mouse to the VM.

I am using an Intel i5 processor, and Linux Guest Additions are fully installed and working. 3D Acceleration is enabled. The problem is extremely finicky when Acceleration is disabled, and I have been able to get the mouse capture to work until I reboot the VM. I have never been able to get it to work with acceleration enabled, though it does depend slightly on the guest.

Host: Windows 10 Pro Guest 1: Ubuntu 16.04 (captured mouse always invisible) Guest 2: Ubuntu 16.04 with Cinnamon 3 GUI (captured mouse always invisible) Guest 3: Kubuntu 16.04 (captured mouse only invisible when mouse integration is turned on)

Other information: This problem is not new to VirtualBox 5.0.22. I have also seen in forums some people comment about this problem in VirtualBox 4.x, but the bug was supposedly resolved.
